  1. 1. Scalable Nonparametric L1 Density Estimation via Sparse Subtree Partitioning

    University essay from Uppsala universitet/Statistik, AI och data science

    Author : Axel Sandstedt; [2023]
    Keywords : density estimation; scalable density estimation; nonparametric density estimation; scalable nonparametric density estimation; L1; L_1; anomaly detection; regression analysis;

    Abstract : We consider the construction of multivariate histogram estimators for any density f seeking to minimize its L1 distance to the true underlying density using arbitrarily large sample sizes. Theory for such estimators exist and the early stages of distributed implementations are available. READ MORE

  3. 2. Leveraging Posits for the Conjugate Gradient Linear Solver on an Application-Level RISC-V Core

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : David Mallasén Quintana; [2022]
    Keywords : Computer Arithmetic; Conjugate Gradient; Posit; IEEE-754; Floating Point; High-Performance Computing; RISC-V; Datoraritmetik; Konjugerad Gradient; Posit; IEEE-754; Flytande Punkt; Högpresterande Beräkningar; RISC-V;

    Abstract : Emerging floating-point arithmetics provide a way to optimize the execution of computationally-intensive algorithms. This is the case with scientific computational kernels such as the Conjugate Gradient (CG) linear solver. Exploring new arithmetics is of paramount importance to maximize the accuracy and timing performance of these algorithms. READ MORE

  4. 3. Mitchell-Based Approximate Operations on Floating-Point Numbers

    University essay from Linköpings universitet/Datorteknik

    Author : Noah Hellman; [2021]
    Keywords : floating-point numbers; approximations; arithmetics; asic; fpga; mitchell;

    Abstract : By adapting Mitchell's algorithm for floating-point numbers, one can efficiently perform arithmetic floating-point operations in an approximate logarithmic domain in order to perform approximate computations of functions such as multiplication, division, square root and others. This work examines how this algorithm can be improved in terms of accuracy and hardware complexity by applying a set of various methods that are parametrized and offer a large design space.

  5. 4. A Data Plane native PPV PIE Active Queue Mangement Scheme using P4 on a Programmable Switching ASIC

    University essay from Karlstads universitet/Institutionen för matematik och datavetenskap (from 2013)

    Author : Love Dahlberg; [2021]
    Keywords : AQM; PIE; PPV; P4; Tofino;

    Abstract : New internet services require low and stable latency, which is difficult to provide with traditional routers and queuing mechanisms. Current routers aim to provide high throughput using large buffers causing considerable network latency under load. READ MORE

  6. 5. Assessment of thermal radiation arithmetic's for jet flames : A study involving generic calculation methods concerning radiation from jet flames with the purpose to determine the safety distance for flame effects

    University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Author : Anne Lee Anderson; [2018]
    Keywords : Jet flame; view factor; incident radiation; radiation temperature; safety distance;

    Abstract : Jet flames are commonly used as flame effects in pyrotechnical shows, and are also a possible risk in industries that uses pressurised flammable gas. For these users it is important to  make fire safety engineering calculations to minimise the risks. This project focus on jet flames that are used in pyrotechnic shows where, e.g. READ MORE
